Online Reservations

Take Bookings & Payments
While You Sleep

Your storefront never closes. Symphony's reservation engine handles the booking, the deposit and the paperwork on its own — so a 2 a.m. inquiry is a confirmed rental by morning.

  • Customers browse and book instantly from a storefront that carries your logo and your rates.
  • Live availability kills double-bookings — every calendar updates the moment a night is claimed.
  • Deposits and payments run themselves through Stripe, then release automatically after return.

Every Pickup, Return
and Dollar on One Screen

Stop guessing what's out and what's owed. Symphony's operator view answers the only four questions that matter each morning — before you've finished your coffee.

Live reservation monitoring

Every scheduled pickup at a glance. No more calling drivers to find out where a car went.

Instant inventory count

See exactly what's available, reserved, or sitting in maintenance — and cut the downtime you're paying for.

Daily return insights

Know what's due back today, what's late, and how many days overdue it is.

Numbers you can act on

Per-vehicle P&L, utilization and top earners tell you which units to buy more of — and which to sell.

If It Moves, You Can Rent It

Built By Operators

We Didn't Study This Business.
We Run It.

Symphony comes out of Supreme Society — a working luxury and exotic rental operation. Every screen exists because we needed it on a Saturday morning with four cars going out and one coming back late. Nothing here is theory.

Questions

Questions You Might
Be Asking

The things operators ask us before they sign up.

Is a credit card required to start the trial?
No. Your 7-day trial opens with an email address and a workspace name — no card, no billing details, nothing to cancel. If Symphony isn't for you, walk away and nothing happens.
What happens when the 7 days are up?
Your data stays exactly where it is. You'll be asked to pick a plan to keep going, and if you don't, the workspace simply goes read-only rather than being deleted out from under you.
What does Early Access mean?
Symphony is live and being used, but we're still shipping features weekly — the "Soon" tags above tell you exactly what's built and what's next. Early Access operators get direct input on the roadmap and lock in launch pricing.
What can I rent with Symphony?
Anything you hand over and expect back. It was built on exotic and luxury cars, but the same model covers boats, jet skis, motorcycles, ATVs, trailers, villas and equipment — nothing in the system assumes four wheels.
Can I import the fleet and customers I already have?
Yes. Bring a spreadsheet of your units and your customer list and we'll help you get it in during onboarding — you shouldn't have to retype two years of history to try new software.
Can my staff use it without seeing everything?
That's the point of the roles. Owners see the money, managers run the fleet, staff handle pickups and returns. Permissions are enforced on the server, not just hidden in the interface — a staff login genuinely cannot read your P&L.
Is my data separated from other companies?
Every workspace is isolated at the database level. Membership in your workspace is what grants access to its records, and that check runs server-side on every single read and write.
How do payments and deposits work?
Through Stripe, under your own Stripe account, so payouts land in your bank and card numbers never touch Symphony or your staff. Deposits are held at booking and released automatically after the unit comes back.
What support do I get?
Real answers from the people who built it and use it daily. Email support@supremesociety.ai and you're talking to an operator, not a script.
